Ear infection: do they actually need antibiotics?

Why "ear infection" doesn't always mean antibiotics

The AAP's current guidance for many ear infections is watchful waiting: pain relief (acetaminophen or ibuprofen) for 48 to 72 hours before starting antibiotics, rather than treating on the spot. The reasoning is straightforward — most ear infections resolve on their own in that window, and holding off avoids unnecessary antibiotic use for infections that were never going to need it.

This isn't every case, and it isn't a decision to make yourself — it depends on your child's age, how sick they seem, and what the eardrum actually looks like, which only a pediatrician can assess.

What you're actually looking for

Ear-pulling gets treated as the classic sign, but it's not reliable on its own — babies pull and rub their ears as a normal self-soothing behavior too, infection or not. It's one piece of a pattern, not proof by itself.

The more telling signs: pain that's clearly worse when lying flat (which is why it often gets dramatically worse at bedtime), fussiness that doesn't settle, trouble sleeping, and — in roughly half of cases — a fever.

This isn't swimmer's ear

An ear infection (otitis media) happens behind the eardrum and is different from swimmer's ear (otitis externa), which is an infection of the outer ear canal, often linked to water exposure, and typically painful specifically when the outer ear is touched or pulled.

You can't reliably tell the two apart from the outside — both cause ear pain — which is another reason this needs an actual look rather than a guess at home.

When it needs same-day care regardless

A baby under 6 months, a high fever, or severe pain generally gets treated right away rather than watched. Beyond that, the watch-vs-treat call itself belongs to your pediatrician — they're the ones who can see the eardrum, which is the actual deciding factor, not anything visible from the outside.
